Bathymophila euspira is a species of sea snail, a marine gastropod mollusk in the family Solariellidae.

The nucleus is translucent, white, and with a sculpture of strong revolving threads, of which that nearest to the suture is most pronounced, and continues, at first sharp, then with slight waves, then with oblique waves like the lay of a stranded rope.

On the body whorl there is a succession of well-elevated pinched-up points forming a band next the suture.

The others disappear on the third whorl, and for the rest the shell is only marked by faint lines of growth here and there, a little more pronounced in the vicinity of the umbilical callus.

The end of the columella (broken in specimens seen so far) apparently form a sort of lump or thickened angle.
